WILLIAM J. RYAN, OF TORONTO, ONTARIO, CANADA.

PIANO-TUNING HAMMER.

Application filed December 15, 1913.

To all whom it may concern:

Be it known that I, WILLIAM JOSEPH RYAN, a subject of the King of Great Britain, resident of 642 King street west, in the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, piano-tuner, have invented certain new and useful Improvements in Piano-Tuning Hammers, of which the following is a specification.

The invention relates to improvements in tuning hammers as described in the present specification and illustrated in the accompanying drawings that form part of the same.

lhe invention consists essentially in the novel construction of a double headed hammer in which the head sockets are devised so as to take the tuning pins in different positions.

The objects of the invention are to avoid the striping of the metal both in the keys and the hammer during tuning operations and generally to provide a simple, serviceable and durable tuning instrument.

In the drawings Figure 1 is perspective view of the hammer. Fig. 2 is a side View of the hammer. Fig. 3 is a perspective view from above.

Like numerals of reference indicate corresponding parts in each figure.

Referring to drawings, 1 and 2 are the hammer heads integral with the back 3 and extending therefrom in V-shape, said back 3 being in ball shape and having extending thereinto from one side thereof the threaded handle hole 4, and from the top the radial pin orifices 5, said orifices being for the in- Specification of Letters Patent.

Serial No. 806,799.

sertion of a suitable pin or lever to facilitate the straightening of bent tuning pins without turning said tuning pins.

6 is a tuning pin socket in the head 1 extending thereinto from the bottom end and of square shape.

7 is a tuning pin socket in the head 2 extending thereinto from the bottom end and of square shape, the sides of the square in the socket 7 being at an angle of substantially 45 degrees in relation to the squares in the side of the socket 6 or vice versa.

8 is a suitable handle screwed into the handle hole 4 for turning the hammer in the operation of tuning.

It will readily be seen that this device can be used with great facility in tuning a piano, for the square sockets will catch the heads of the tuning pins very readily and in any position, that is to say, either one of the heads, for the angles of the square holes are in different arrangement which will permit reaching the tuning pin easily.

What I claim is:

A tuning hammer comprising a ball shaped back, a handle screw threaded into said back, a pair of heads extending in V-shape from said back and at right angles to said handle, square tuning pin sockets in said heads and radial pin holes extending into said back opposite said heads.

Signed at the city of Toronto this Qth day of July, 1913.
